Attributing harvest information with unique identifiers

ABSTRACT

Systems and methods allow units of produce to be traced back to the fields in which the produce was grown. In the field, a harvest form is completed with harvest information at the time of the harvest. In some instances, labels having unique codes are used to label the produce in the field, and two additional labels are placed on the harvest form to associate a range of unique codes with the harvest information on the form. In other instances, the produce packages arrive at the field already marked with the unique codes. The empty marked packages are themselves packed in boxes, where each box has a unique box code. The unique codes on the empty marked packages are associated in advance with the unique box code on the box, and in the field the unique box code is associated with the harvest information.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to the field of consumer product traceability, and more specifically to unit-level traceability for products such as fresh produce.

2. Description of the Prior Art

When a problem with contaminated food arises, a significant issue is identifying the source of the contamination. With contaminated produce, being able to quickly identify the growers and the specific fields that are the source of the contamination is important to enable prompt remedial action to protect the public health and to restore public confidence in the food supply chain. It is also desirable to be able to easily identify which produce is affected and which is safe. Restoring public confidence and being able to readily identify unaffected produce help prevent large declines in sales volumes and the unnecessary destruction of substantial amounts of safe produce.

Presently, the complex and global supply chain makes the process of identifying the sources of the contaminated produce slow and cumbersome.

SUMMARY

An exemplary method for associating information with harvested produce is provided. The exemplary method comprises recording harvest information on a harvest form, affixing a pair of labels to the harvest form and affixing individual labels to produce being harvested, where each of the labels includes a unique code. The method further comprises creating a record that associates the harvest information with a range defined by the unique codes on the pair of labels. In some embodiments, affixing the pair of labels to the harvest form and affixing individual labels to produce being harvested comprises removing a first label from a roll of labels and affixing the first label to the harvest form, removing the individual labels from the roll after removing the first label and affixing the individual labels to produce being harvested, and after removing the individual labels from the roll, removing a last label from the roll and affixing the last label to the harvest form.

In various embodiments, produce being harvested comprises bulk loose produce or item-level packages such as bags, trays, and clamshells. Also in various embodiments the unique codes can comprise cipher texts of plain text codes where the plain text codes follow a sequence or pattern. In some of these embodiments, the range defined by the unique codes on the pair of labels is a range defined between the plain text codes corresponding to the unique codes on the pair of labels.

The method can further comprise, in some embodiments, generating a batch of unique codes and producing a set of labels including unique codes from the batch, where the set of labels includes the pair of labels and the individual labels. In some of these embodiments, producing the set of labels comprises creating a roll of the labels. Also in some of these embodiments, generating the batch of unique codes includes encrypting plain text codes that are related by a sequence or pattern.

Another exemplary method comprises generating a batch of unique codes, marking a plurality of item-level packages with unique codes from the batch to produce a plurality of marked item-level packages, labeling a box with a unique box code, filling the box with the marked item-level packages, and creating a record that associates the unique box code with the marked item-level packages within the box. Marking the plurality of item-level packages can comprise, in some embodiments, affixing a label to each of the item-level packages, where each label includes a unique code from the batch. Marking the plurality of item-level packages can also comprise printing a unique code from the batch on each item-level package. Labeling the box with the unique box code can include affixing a box label including the unique box code to the box, and in some of these embodiments the box label includes one or more detachable tags, each tag including the same unique box code.

Another exemplary method for associating information with harvested produce comprises receiving a box including a plurality of marked item-level packages, each marked item-level package including a unique code marked thereon, the box further including a label including a unique box code. The method further comprises recording harvest information on a harvest form, packing the marked item-level packages with produce, and creating a record that associates the harvest information with the unique box code. In some embodiments, the label further includes one or more detachable tags, each tag including the same unique box code. Some of these embodiments further comprise detaching a detachable tag from the label and affixing the tag to the harvest form.

DETAILED DESCRIPTION OF THE INVENTION

The present disclosure is directed to improving the traceability of goods through the supply chain, and in particular, the traceability of produce from the field to the consumer. Traceability of produce back to the growing fields is implemented by marking loose bulk produce, clamshells, bags, boxes, trays, cartons, and other forms of item-level packaging with unique codes. The unique codes can follow a known sequence or pattern, or the unique codes may appear random but are actually the encrypted versions of underlying codes that follow a known sequence or pattern. Marking can be done with labels that have been pre-printed with the unique codes, in some instances. Towards the goal of traceability, the unique codes are further associated with information such as harvest information. A unique code read from an item of produce at a later date can be used to find the previously associated information. It will be appreciated that produce is used herein as an example, but the present invention can equally be applied to other food item, pharmaceuticals, and so forth, where it is important to be able to trace units back to their sources.

In the fields where produce is harvested, data entry is not a particularly convenient task. Accordingly, in some embodiments harvest forms and rolls of labels are provided, where the unique codes on the labels follow the sequence or pattern. The labels are removed from the rolls and applied to the loose bulk produce or item-level packaging, and harvest information is also recorded on the harvest form. Before any items are labeled, however, the first label from each roll in use is removed and placed on the harvest form. When the roll is no longer being used, for example, because of a harvesting crew change, one final label is removed from the roll and placed on the harvest form next to the first label from that roll.

In other embodiments, empty item-level packaging is marked with the unique codes, either by printing, scribing, or with labels, as above. In these embodiments, a box filled with these marked item-level packaging is brought to the field and a harvest form is completed. The box, in these embodiments, includes a label with a unique box code, and in some further embodiments the label also includes one or more detachable tags, where each of the tags also includes the same unique box code. The unique codes marked on the item-level packaging are associated with the unique box code. When the marked item-level packaging from the box are filled with produce, the unique box code is noted on the harvest form, for example, by detaching a tag from the label on the box and affixed the tag to the harvest form.

Harvest forms are then brought to a data entry location, such as an office, where the information from the harvest forms is used to create electronic records that are stored in a database, for example. In those embodiments that affix pairs of first and last labels to the harvest forms, the unique codes for each pair, or the corresponding underlying decrypted codes, are associated with the information from the harvest form. In those embodiments that employ the unique box code, the unique box code is associated with the information from the harvest form. The unique box code provides a link between the records that associate the unique box code with a range of unique codes on item-level packaging and the further records that associate the unique box code with information from the harvest form. It will be appreciated that performing the data entry in a centralized location provides several advantages. For example, less infrastructure is required, and in particular, fewer scanners. Those scanners, in turn, are not subjected to harsh field conditions that tend to cause scanners to have to be replaced prematurely. Centralized data entry, and the methods described herein generally, have little impact on the workflow in the fields.

FIG. 1 shows a pre-printed harvest form 100 according to an exemplary embodiment of the present invention. The harvest form 100 provides a convenient way to record information in the fields and includes spaces to place labels used for marking individual items of produce, or item-level packaging such as bags, clamshells, cartons, baskets, and so forth. The harvest form 100 can include various types of information. For example, the harvest form 100 can include information that does not vary from one harvest to another, such as the type of produce—honeydew melon in the exemplary harvest form 100. Information of this type can be pre-printed on the harvest form 100, in some embodiments.

The harvest form 100 also can include a region 110 for recording information such as the harvest event data for the particular harvest. Additionally, each harvest form 100 includes a unique harvest form code 120 that is different for each harvest form 100, in some embodiments. The unique harvest form code 120 can also be pre-printed on the harvest form 100, in some embodiments. The unique harvest form code 120 can also be stamped on, or otherwise applied to the harvest form 100, at the time of harvesting. In some embodiments, the unique harvest form code 120 is provided in a human-readable format, as shown, or a machine-readable format, or both. The unique harvest form code 120 can also be stamped or applied to the harvest form 100 at the time of harvesting.

The harvest form 100 further includes one or more rows 130, where each row 130 is intended to receive a pair of labels 140. The labels 140 are described in greater detail with respect to FIG. 2, below. In some embodiments of the harvest form 100, the spaces provided in the rows 130 for the labels 140 can each include a pre-printed dummy code 150 that is intended to be covered by the labels 140, but if not covered can be read to show that a label 140 was missing from the space.

FIG. 2 shows the pre-printed label 140 of FIG. 1 according to an exemplary embodiment of the present invention. Each label 140 includes a unique code that can be represented in a human-readable form 210, in a machine-readable form 220, or both. In one embodiment, the unique code in the human-readable form 210 comprises a 24 digit number. The unique code in the machine-readable form 220 can comprise a data matrix, as shown, or a GS1 databar code, for example. Each label 140 may also include a UPC code 230 corresponding to the produce to be harvested. In some embodiments, the unique code in the machine-readable form 220 can comprise both the UPC code 230 and the unique code. Labels 140 can be provided on rolls or sheets, for example. Further detail regarding the use of the labels 140 and the unique codes are provided below with respect to FIG. 3.

FIG. 3 provides a flowchart representation of a method 300 for associating information with harvested produce according to an exemplary embodiment of the present invention. The method 300 comprises a step 305 of generating a batch of unique codes and a step 310 of producing a plurality of labels 140 including the unique codes generated in step 305. The method 300 also comprises a step 315 of recording harvest information on a harvest form 100, a step 320 of affixing labels 140 to both the harvest form 100 and to produce being harvested, and a step 325 of associating harvest information with unique codes in a searchable database.

In various embodiments, steps 305 and 310 are performed by a first party that supplies labels 140 and harvest forms 100, while steps 315, 320, and 325 are performed by a second party, such as a produce grower or packer, which receives the labels 140 and the harvest forms 100 from the first party. In some of these embodiments, the labels 140 and harvest forms 100 are custom made for the second party upon request. Also in some embodiments, the first party produces the harvest forms 100 and/or the labels 140 at the work site of the second party through a secure computing system. In still other embodiments, each of the steps 305-325 of the method 300 are performed by the same party. It is noted steps 315 and 320 can occur in either order or can be performed together.

Step 305 of the method 300 comprises generating one or more batches of unique codes. A batch of unique codes is a plurality of codes that follow a sequence or pattern, or a plurality of codes that are the encryptions of other codes that follow a sequence or pattern. For clarity, in those embodiments in which the unique codes comprise the encryptions of other codes, the codes that are related to one another and that are encrypted are referred to herein as plain text codes while the encryptions thereof may be referred to herein as either unique codes or cipher text codes. An exemplary batch of unique codes can comprise, for example, a sequence of serial numbers that have been encrypted. Methods for generating plain text codes and for generating unique codes therefrom are described in detail in related U.S. patent application Ser. No. 11/619,747 noted above.

It is noted that generating unique codes that are cipher texts and that include large numbers of digits provides certain advantages. Where the number of digits is 12, for example, the total possible number of unique codes is 10 to the power of 12, thus, the total number of unique codes ever in use will be a small fraction of the total possible number of unique codes. It is therefore unlikely that a person would be able to guess a valid unique code. The unpredictability of the unique codes can be important for vendor promotions, for example, when there is a valuable benefit, such as a coupon, provided when a customer submits a valid unique code or is reimbursed for poor product quality or a recalled product. If the unique code was predictable, customers could attempt to defraud the system by guessing codes for units of produce that they had not purchased and obtain the coupons. Furthermore, when the set of valid unique identifiers comprises a small fraction of the total possible number of unique codes, it is much less likely that someone will submit an unintended, yet valid unique code by mistyping a valid unique code.

In various embodiments, the number of unique codes in a batch is dictated by the needs of the grower or packer. For instance, a batch can include a larger number of unique codes to accommodate a large lot size, or a small number of unique codes to accommodate a small lot size. In some instances, step 305 includes receiving a request for a batch size, for example, a request for a batch of 1,000. The request can come from a produce grower or packer, for instance. It will be appreciated that tailoring batch size to lot size can be convenient in some instances, but that there is no requirement that they be the same. Accordingly, the batch size can be much greater or smaller than the lot size.

Step 310 comprises producing a plurality of labels 140 where each label 140 includes one of the unique codes from the batch generated in step 305. The plurality of labels 140 produced in step 310 can comprise one or more rolls of labels 140 or a number of sheets of labels 140, for example. On a roll of labels 140, the unique codes on successive labels 140 either follow a sequence or pattern or are the cipher texts of plain text codes that follow the sequence or pattern. In the latter instance, the unique codes on successive labels 140 on a roll will appear to be random, but when decrypted will result in plain text codes that follow the sequence or pattern. The same can be applied to the unique codes of successive labels 140 on sheets of labels 140.

Step 315 comprises recording harvest information on a harvest form 100. The harvest information can be recorded by a harvest supervisor, for instance. Harvest information can include, for example, the ranch or farm, the field and section harvested, the crew harvesting the produce, the harvest time and date, the weather conditions, the lot number, type of produce harvested, brand name, seed variety, special notes, and so forth. As provided above, some of this information may not vary and can be pre-printed on the harvest form 100.

Step 320 of method 300 comprises affixing labels 140 to both the harvest form 100 and to produce being harvested. Here, “produce being harvested” refers to either loose bulk produce or item-level packaging filled with produce. In some embodiments, field workers are provided with rolls of labels 140. Each time a roll of labels 140 is used by a field worker, the field worker peels a first label 140 off of the roll and affixes that label 140 to a row 130 of the harvest form 100. In the exemplary harvest form 100, the first label 140 is placed in the left column of the harvest form 100. The field worker then affixes successive labels 140 from the roll or sheet to produce being harvested. Each loose bulk produce item or item-level packaging of produce receives one label 140 in step 320.

When the field worker reaches the end of a roll, the field worker takes the final label 140 of the finished roll and affixes that last label 140 to the same row 130 of the harvest form 100, such as the right column in the illustrated example. Similarly, if the field worker has finished packing produce in the harvest associated with the particular harvest form 100 but still has a partially used roll, the field worker takes the next unused label 140 from the partially used roll, and affixes that label 140 to the same row 130 of the harvest form 100. Where the roll is only partially used, the same roll can be used again with the same harvest form 100 or with a different harvest form 100. Where a field worker finishes a roll before completing the harvest associated with the harvest form 100, the field worker can continue with a new or a partially used roll, again by affixing a first label 140 to the harvest form 100, affixing successive labels 140 to produce being harvested, and then affixing a last label 140 to the harvest form 100. It will be appreciated that method 300 does not require the same person to perform all of the tasks of the step 320. For instance, a field supervisor can affix the first labels 140 to the harvest form 100 before providing the rolls to the field workers.

Step 325 comprises creating a record that associates the harvest information recorded on the harvest form 100 with one or more pairs of unique codes and/or any plain text codes that correspond to the unique code pairs. The record can be created with logic, such as a database application, and stored in a searchable database, for example. Creating the record can include, in some embodiments, manually entering the harvest information through a graphical user interface. In some other embodiments, creating the record can include automatically entering the harvest information with a reader configured to read the harvest form 100, such as by recognizing marked checkboxes, decoding barcodes, or performing optical character recognition, for example. In some embodiments, step 325 also comprises associating the unique harvest form code 120 with the created record.

FIG. 4 illustrates a graphical user interface 400 for entering harvest information, according to an exemplary embodiment of the present invention. The graphical user interface 400 can comprise a web page viewed with a web browser on the display of a personal computer, for instance. In some embodiments, the web page is served by a remote server and the record created in step 325 is created and stored remotely. In some of these embodiments, a party other than the grower or harvester maintains the created records as a service. The remote server can be a host in a host-client relationship with a client computing system used to enter the harvest data.

It can be seen in the exemplary graphical user interface 400 that the harvest information can be automatically entered by reading the harvest form 100, as previously noted. It can also be seen that the graphical user interface 400 allows a user to manually enter missing data, or correct erroneous data. In various embodiments, pairs of unique codes on the harvest form 100 are manually entered through a graphical user interface or automatically entered with a fixed or handheld scanner such as a barcode reader, for instance. The exemplary graphical user interface 400 of FIG. 4 shows pairs of unique codes that were entered automatically. In some embodiments of the graphical user interface 400, unique codes that were erroneous entered can be selected and removed.

In some embodiments, the unique codes are cipher texts of plain text codes, as illustrated in FIG. 4, and in these embodiments step 325 can further comprise decrypting the unique codes and associating the resulting plain text codes with the record. The further step of decrypting the unique codes and associating the resulting plain text codes with the record can be performed at the time the record is created or at some later time. For example, in some embodiments the record associating the harvest information and the pairs of unique codes is created locally, then the record is communicated to a remote computing system, such as the remote web server mentioned above, that is configured to perform the decryption, save the plain text codes to the record, and save the record in a searchable database. In some embodiments of the method 300, records created in step 325 only associate the plain text codes with the harvest information, and do not retain the unique codes themselves. In either case, given a unique code, the corresponding harvest information can be readily determined from the records.

FIG. 5 provides a flowchart representation of a method 500 for associating information with harvested produce according to an exemplary embodiment of the present invention. The method 500 comprises the step 305 (FIG. 3) of generating a batch of unique codes and a step 510 of marking a plurality of item-level packages with the unique codes. The method 500 further comprises a step 515 of providing a box packed with the marked item-level packages and further comprising a unique box code. The method 500 also comprises a step 520 of creating a record that associates the unique box code with the marked item-level packages within the box. In some embodiments, the steps just described are performed by a first party that supplies item-level packaging, while the following steps of the method 500 are performed by a second party such as a grower or harvester. Accordingly, method 500 also comprise a step 315 (FIG. 3) of recording harvest information on a harvest form 100, a step 525 of packing the marked item-level packages with produce, and a step 530 of creating a record that associates the unique box code with the harvest information. Steps 305 and 315 in the method 500 can both be performed as described above with respect to FIG. 3. Steps 515 and 520 can be performed in either order or together, in various embodiments.

Step 510 comprises marking a plurality of item-level packages with the unique codes generated in step 305 to produce a plurality of marked item-level packages. The item-level packages can comprise bags, clamshells, cartons, baskets, and the like. The item-level packages can be marked with labels such as label 140, or by various printing techniques, or by laser engraving, for example.

Step 515 comprises providing a box including the marked item-level packages and further comprising a unique box code. Here, the unique box code is a unique code assigned to the box and marked on the exterior of the box. The unique box code can be marked with a label that includes the unique box code, or by various printing techniques or by laser engraving, for example. The unique box code is machine-readable, in some embodiments. Step 515 can include packing the box with some or all of the marked item-level packages produced in step 510. It will be understood that the marked item-level packages produced in step 510 can be distributed across many such boxes so long as the unique codes on the item-level packages within a particular box, or the underlying plain text codes if the unique codes are cipher texts, follow the series or pattern.

Step 520 comprises creating a record that associates the unique box code with the marked item-level packages within the box. The record can be created with logic such as a database application and the record can be stored in a searchable database, for example. Step 520 can comprise entering the unique box code and entering the unique codes from the first and last item-level packages placed in the box. Entering the unique box code can be performed manually through a graphical user interface similar to the graphical user interface 400, or automatically with a fixed or handheld scanner, for instance. Likewise, entering the first and last unique codes from the marked item-level packages can be performed automatically by scanning the unique codes or manually through a graphical user interface. Further disclosure regarding packing boxes with marked item-level packaging can be found in U.S. Provisional Patent Application No. 61/080,121 filed on Jul. 11, 2008 and entitled “Mobile Table for implementing Clamshell-to-Case Association” which is incorporated herein by reference.

In step 520, creating the record that associates the unique box code with the marked item-level packages within the box can comprise, in some embodiments, associating the unique box code with the first and last unique codes marked on the item-level packages in the box. In other embodiments, creating this record comprises associating the unique box code with the plain text codes that correspond to the first and last unique codes marked on the item-level packages.

Step 525 comprises packing the marked item-level packages with produce. Step 525 can be performed manually or through the use of automated packing equipment, for example. The filled item-level packages can then be aggregated into trays or cases for distribution through the supply chain to the retailer.

Step 530 comprises creating a record that associates the unique box code with the harvest information from the harvest form 100 recorded in step 315. The record can be created with logic such as a database application and the record can be stored in a searchable database, for example. As above, the record can be created and stored remotely. While the records created in steps 520 and 530 can be created by different logic and stored in different databases, in various embodiments these records are created by the same logic and/or stored in the same database.

In some embodiments, step 530 includes writing the unique box code on the harvest form 100. Later, the record can be created by manually or automatically entering the harvest information and the unique box code in a manner analogous to that described above with respect to step 325. In further embodiments, the unique box code and the unique harvest form code 120 are both scanned in the field to create a record that associates the two. Later, a record is created with the harvest information by manually or automatically entering the harvest information in a manner analogous to that described above with respect to step 325, and the unique harvest form code 120 is used to find the associated unique box code so that the unique box code can be associated with the record of the harvest information.

FIG. 6 shows a pre-printed box label 600 according to an exemplary embodiment of the present invention. The box label 600 facilitates the association of unique box codes with harvest information in some embodiments, as described below with reference to FIG. 7. The box label 600 can include an adhesive backing and comprises several fields of information including the unique box code 610, which in the illustrated embodiment is presented in both human-readable and machine-readable forms, though either one of these formats can be sufficient. The box label 600 also comprises one or more detachable tags 620 that also each comprise the unique box code 610. The detachable tags 620 can be adhesive-backed, in some embodiments. In the illustrated embodiment, the detachable tags 620 can be peeled off of the box label 600, while in other embodiments the detachable tags 620 can be separated from the box label 600 along perforations, for example. It will be appreciated that an exemplary box label for the method 500 of FIG. 5 would be box label 600 without the detachable tags 620. In some of those embodiments, the box label can be printed or laser engraved directly onto boxes.

FIG. 7 provides a flowchart representation of another method 700 for associating information with harvested produce according to an exemplary embodiment of the present invention. The method 700 differs from the method 500 in that method 700 is specifically directed to those embodiments in which the box label 600 includes the detachable tags 620. Accordingly, method 700 includes a step 710, in place of step 515, in which a box is provided including the marked item-level packages and further comprising a label 600 including a unique box code and one or more detachable tags 620 each including the unique box code. Additionally, the method 700 includes the additional step 720 comprising detaching a detachable tag 620 from the label 600 and affixing the tag 620 to the harvest form 600.

After step 720, the step 530 comprises creating a record that associates the unique box code with the harvest information by manually or automatically entering the harvest information from the harvest form 100 and the unique box code from the tag 620 on the harvest form 100, essentially as described above with respect to the method 500.

It will be appreciated that according to the method 700, multiple harvest forms 100 can include tags 620 with same unique box code leading to the creation of multiple records in step 530 in which potentially different harvest information becomes associated with the same unique box code. As a result, if the records are searched for a particular unique code, several matching records may be found. This is referred to as over-association, and in some situations over-association is advantageous.

For example, when investigating a food contamination situation, while it may not be possible in these embodiments to know which of the several records found for a particular unique code is the correct record of the harvest for that unique code, it is useful to know that several harvests might be closely related and each harvest is worth further consideration. Additionally, when a consumer requests harvest information for a particular unit of produce, several harvest records may be returned. However, in most instances the several records will be for harvests all within a general vicinity, within a short period of time, and under very similar conditions.

It should be noted that the harvest information records created in methods 300, 500, and 700 can be updated with additional information not provided on the harvest form 100. Weather information is one example, described in greater detail below. Customer satisfaction information, also described in greater detail below, can also be added as it is acquired. Other records, such as those pertaining to chemical and pesticide use on the field, temperature during transportation, and distribution, for example, can be linked to the harvest information records, as well.

FIG. 8 provides a flowchart representation of optional steps that can be included in any of the exemplary methods 300, 500, 700 provided with respect to FIGS. 3, 5, and 7, according to exemplary embodiments of the present invention. More specifically, the steps described with reference to FIG. 8 can be sub-steps of the step 530 in both methods 500, 700 or of the step 325 in method 300.

In a step 810, a range of plain text codes corresponding to a pair of unique codes is determined. For example, each of the pair of unique codes is decrypted. The decryption can be performed by the same logic that creates and stores the records, and contemporaneously with creating and storing the records, in some embodiments. In other embodiments, the pair of unique codes is decrypted by different logic, potentially of a different computing system, potentially at a later time, and potentially at a remote location. For instance, a record can be created by a computing system at a field office and then communicated to a more centralized office, such as a corporate office or to a second party that provides product traceability services. These later embodiments offer the advantage of tighter control over decryption keys and also centralized record-keeping. In some instances, the range of plain text codes excludes those plain text codes that are associated with the pair of unique codes from the first and last labels affixed to the harvest form 100 and not affixed to produce.

In a step 820, errors are detected and fixed. One way in which errors can be detected is by comparing the ranges between the pairs of unique codes, or between the corresponding plain text codes, to the number of labels 140 on the rolls. For instance, the size of the rolls can be selected so that in most instances the field workers will completely use each roll during a harvest. For a particular type of produce, for example, each roll may comprise 1000 labels. In this case, the first and last unique code in a row 130 on the harvest form 100 will most commonly be the first and last labels of the roll. When first and last unique codes span a range of exactly 1000 labels 140, there is a high degree of confidence that the record is accurate.

One error that is readily detected and corrected is where the first and last labels 140 for a particular roll have been transposed. Here, the range of the unique codes, or of the plain text codes, will be backwards. If the absolute value of the range equals, or is close to, the number of labels 140 on a roll, then the values can be reversed with a high degree of confidence.

When the range spanned by the first and last unique codes exceeds the number of labels 140 on an entire roll, then it is likely that there is an error wherein the first label came from one roll and the last label 140 improperly came from another roll. In some embodiments, such transposed labels 140 on a harvest form 100 can be readily determined because switching two last labels 140 creates two ranges that each equals the number of labels 140 on the rolls. In situations where transposing labels 140 does not produce two corrected ranges that both equal the number of labels 140 on a roll, then a degree of confidence can be determined for various alternatives and the alternative with the highest degree of confidence can be selected. In some embodiments, finding and correcting errors can consider more than a single harvest to find labels 140 incorrectly placed on the wrong harvest forms 100.

In other embodiments, such errors are not corrected, over-associating unique codes with harvest information. This is done on the theory that it is beneficial to know all the harvest information that may be associated with a unique code and thereby reliably exclude all other harvest information as not being associated with the unique code. In some embodiments, associations of unique codes with a harvest are only removed when the possibility can be positively ruled out. In other cases, only certainty above some lesser confidence threshold is required to rule out such an association.

Other methods of the invention pertain to utilizing the records created in methods 300, 500, and 700. In some embodiments, a unique code is received by a host computing system, for example, through a webpage served by a remote server. The URL for the web site can be printed on the label 140, for instance. The unique code can come from a customer at a kiosk in a supermarket, a customer using a home computer, a retailer, a distributor, a government agency, a grower, or a harvester, for example. The unique code can be entered manually by reading the human-readable form 210, or by scanning the machine-readable form 220 with a barcode scanner, for example. In some cases, the machine-readable form 320 can be imaged using a cell phone camera, or submitted using the Short Messaging Service (SMS) or another mobile phone-based communication service.

In some instances, the type of entity submitting the unique code can be determined from an IP address, a login page, etc. Based on the type of entity, some or all of the harvest data can be made available. For instance, a retail customer would have access to information about the location of the field, but not the names of workers, the date of the harvest, and so forth. All harvest information, on the other hand, would be accessible to an investigator from the FDA.

Upon receiving the unique code, where the unique code comprises a cipher text, the host computing system decrypts the unique code to determine the corresponding plain text code. The records are then searched to find a range of plain text codes that includes the one for the submitted unique code. In some embodiments, the range directly correlates to a record of harvest information. In other embodiments, the range correlates to a record that associates the range with a unique box code. Here, further records are searched to find those records that correlate that unique box code with harvest information.

Once the harvest information has been retrieved, that information can be used to ascertain other information. For example, where the harvest information includes the location of the field and the date and time of the harvest, this information can be used to retrieve weather information at the time of harvest from National Weather Service records. It will be appreciated that such further information need not only be determined upon a particular request, but can be associated with the record of the harvest information at the time the record was created, or any time thereafter. In some embodiments, weather information for an entire growing season can be associated with the harvest records.

Additionally, once the harvest information has been determined for a particular unique code, other information can be determined. For example, a customer can request an estimate of the “food miles” for the produce, an estimate of how far the food travelled to reach the customer. The customer can enter an address or a zip code to establish one end point, the field of the harvest comprises the other end point, and the distance between can be readily estimated. In some embodiments, travel time from the field to the retailer can be provided or estimated, while in other embodiments this is considered proprietary information and not made available to the public.

Also, retailers, distributors, growers, and harvesters, for instance, can collect customer satisfaction information from the customers that submit unique codes. The customer satisfaction information can include information collected from the customer, such as the retailer from which the produce was purchased, the date the produce was purchased and consumed, and a satisfaction rating for the quality of the produce.

The customer satisfaction information can then be correlated with the harvest information for the submitted unique code, such as the field the produce was grown on, the date that the produce was harvested, the retailer that sold the produce, the region that the produce was sold, the time of day the produce was harvested, the weather at the time of harvest, the transit time from harvest to consumption, and other factors that may be related directly or indirectly to customer satisfaction levels. This information can be analyzed by retailers, for example, to identify those growers that yield the greatest customer satisfaction levels, to provide feedback to growers as to the conditions which seem to yield the best results, and to adjust the supply chain to have transit times with better customer satisfaction levels.

In some embodiments, incentives can be provided to encourage customer participation in providing information. For example, promotions, discounts, special offers, and coupons can be offered as incentives.
